Returns a . separated path containing all names of the pin within its main memory owner / storage. This is typically used to create an offset pointer within memory (FRigVMRegisterOffset). So for example for a PinPath such as "Node.Transform.Translation.X" the corresponding SegmentPath is "Translation.X", since the transform is the storage / memory.
